Browserbase
4.4
Browserbase runs cloud browsers for agents that need to click through the web, alongside fetch and search APIs, agent identity for accessing sites that require login, and a model gateway. It maintains Stagehand, an open-source SDK for browser automation. Free gives 3 concurrent browsers, 1 browser hour and 3 agent runs; Developer is $20 a month and Startup $99.

What it is good for
- Agents that must interact with sites lacking an API
- Scraping behind authentication
- Running many browser sessions in parallel
- Teams that do not want to operate headless browser infrastructure
Strengths and trade-offs
Strengths
- Removes the operational burden of running headless Chrome at scale
- Agent identity handles the login problem that breaks most scraping
- Stagehand is open source and usable independently
Trade-offs
- Free tier's one browser hour is an evaluation allowance
- Browser automation remains fragile when sites change
- Check the terms of service of sites you automate
Editors' review
Someone else's problem now
Running headless browsers at scale means fighting memory leaks, zombie processes and detection. Paying $20 to make that someone else's job is straightforwardly good value.
The fragility does not go away. Sites change, selectors break, and the maintenance is still yours.
Verdict
Worth it the moment browser automation becomes more than a script. The free tier shows you quickly.
